Catie Chang and I would like to use 3dREMLfit to regress out cardiac and respiratory phase by slice with the -slibase option. Catie is generating the .1D input matrix that is necessary for this option with a custom Matlab routine.
Because we are not using 3dDeconvolve to generate the input matrix, which would also contain the censoring, can a -censor option be used directly in 3dREMLfit? If yes, even though we are correcting by slice, can the censor file be in TRs, or would it need to be upsampled according to the number of slices per volume? If no, how might we proceed? Thank you.
